OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 417,639, dated December 1'7, 1889.

Application filed June 28, 1889.

[ all whom it may concern.-

Be it known that I, OLIVER I. HESS, a citizen of the United States, residing at Scottdale, in the county of IVestmoreland and State of Pennsylvania, have invented a new and.

useful Oil Can or Stand, of which the follow ing is a specification.

This invention has relation to oil cans or stands; and among the objects in view are to provide the same with an automatic alarm, whereby the alarm will be sounded when the time for cutting off the supply arrives.

The invention consists in a can the upper enll of which is provided with an air-tight stopper threaded thereon, a spout projecting from the can and provided with a surrounding air-tube, an air-nipple projecting from the can above the spout, and an elastic sleeve loosely connecting the nipple and air-tube, whereby, in the act of pouring or emitting the contents of the can through the spout, air will be drawn through the air-tube, the elastic coupling, and nipple into the can, to fill the vacuum caused by the egress of oil, and thus sound the alarm, which, in the present instance, is formed of apiece of flexible flabby elastic tubing.

Referring to the drawings, Figure l represents a perspective of an oil can or stand constand; Fig. 3, a detail in section of the acousticalarm.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents an ordinary oil-can of any shape desired, at theupper end of which there is mounted a screw-threaded stopper 2- and an interposed rubber washer 3. The upper portion of the can is preferably provided with a cone-shaped dome 4; but it may be otherwise formed, if desired. From the dome, at one side thereof, there projects a vertically and laterally disposed eduction-spout 5, the upper portion of which is bent at an angle, as at 6, to the remainder of the spout, and is in about a horizontal line with a nipple 7, communicatin g with the interior of the dome and projecting laterally from the apex thereof.

Serial No. 315,852- (No model.)

thereto an inverted-U-shaped air-tube 8, the front end of which terminates flush with the end of the spout, said tube projecting slightly beyond thelateral portion 6 at the rear of the spout and terminating in a nipple 9 in ahorizontal line with the nipple 7.

10 represents a coupling, which in this instance forms the acoustic alarm, and the same is formed of a sleeve made of verylight thin rubber, the ends 11 of which are connected with the nipples 7 and 9, and inter-. mediate said ends the walls of the rubber fold upon themselves or lie flat.

The operation of my invention is as follows: To fill a lamp or other receptacle for oil, the bent portion 6 of the spoutis introduced into the oil-receiving opening of the vessel and the oil permitted to flow from the can 1 therein. The proportion of the bent portion 6 is such that the end thereof, when introduced into an oil-receptacle, will be a short distance below the mouth of the receptacle and at about a height which is desired the oil should rise to. As the oil passes in a vacuum is formed in the can 1, and the air is drawn in' through the air-tube H, coupling 10, and nipple 7 to take the place of the escaping oil. In so doing the walls of the sleeve lying together are forced apart, and ahorn-sounding noise is made, which continues until the oil rises even with and closes the air-tube 8, thereby arresting the flow of oil and stopping the sound, when it will be apparent that the vessel is filled, and thus any likelihood of overrunning the vessel is avoided.

By locating the alarm upon the outside of the can I obviate any liability of said alarm becoming oil-clogged, and thereby rendering the same inoperative. Furthermore, a clearer and more distinct alarm is given, which is of importance should it be necessary to emit the oil in a fine stream.

By reason of the walls of the coupling 10 folding one upon the other when the can is at rest I efliciently cut off the interior of the can from the outer atmosphere, and in this manner prevent the escape of disagreeable odors through the air-passages.

A further advantage of the flexible flabby coupling is that in tilting the can, as is often the case when filling small vessels, the said coupling can be compressed by the thumb and finger of the operator, so as to prevent admission of air and any consequent premature emission of oil.

Having described my invention,what I claim is- 1. An oil-can provided with a spout, an air tube mounted on the spout and terminating in a nipple, and an air-tube mounted on the can and connected with the nipple by an acoustic alarm, substantially as specified.

2. An oil-can provided with a spout provided with an air-tube terminating at its rear end in a nipple, a nipple projecting from the can, and a flabby flexible coupling, as 10, connecting the nipples, the walls of the coupling intcrinediate the nipples being designed to normally close one upon the other, substantially as specified.

3. An oil-can provided with a spout thcupper portion of which is bent at an angle to the main portion, an inverted-Usl1aped airtube mounted on the bentportion and mounted on its front end flush therewith and having its rear end extended beyond the bent portion to form a nipple, and a nipple projectingfrom the upper end of the can in line with the air-tube, and the rubber coupling 10, connecting the nipples, the walls of which normally lie one upon the other, substantially as specified.

4:. A can provided with an air-tight stopper screwed thereon, a spout projecting from the can and provided with asurrounding airtube, an air-nipple projecting from the can above the spout, and an elastic sleeve loosely connecting the nipple and air-tube, whereby in the act of pouring the contents of the can through the spout air will be drawn through the air-tube, the elastic coupling, and nipple into the can to fill the vacuum caused byoil, and thus sound an alarm, set forth.

In testimony that I claim the foregoing as my own I have hereto affixcd my signature in presence of two witnesses.

OLIVER I. HESS.
